dam yea thats legit
basically any thing causing hyoptension(e.g nitrates..hydralazine..minoxidil drugs without ANS pharm or a1 blockers) or drugs that have pressor effects(a1 stimulation..like phenylephrine possibily) affect barorecpetors a increase in BP(HTN or caroitid massage) is sensed n the message of HTN causes INCREASE in AFFERENT(sensory) barorecpetor firing=INCREASE efferent activity of parasympahetic to decrease SA node firing and AV conduction n total opp for hypotension=DECREASE aff. barorecpetor firing=INCREASE eff sympathics via CN 9 and increase HR and increase CO correct me if um wrong
